High Quality Oil Displacement With High Molecular Weight Polyacrylamide Industrial Test

In order to meet the oilfield eor demand for the diversity of polyacrylamide products,meet the requirements of the quality of product. In a company without a fully mature production technology, the molecular weight of polyacrylamide in the use of the existing production technology, production line without a big technical transformation, no increase in the cost of production. By optimizing the process parameters, replace part of the new catalyst to produce high quality high molecular weight polyacrylamide products. In order to solve the displacement with high molecular weight polyacrylamide product percent of pass of first class of the quality indicators the problem of low.(A total of 15 indicators, respectively are product appearance, solid content, granularity, viscosity average molecular weigh, degree of hydrolysis, solution rate, Screen mesh coefficient,residual monomer,water insoluble matter,filtration factor,viscosity,intrinsic viscosity,Shear viscosity retention rate, Stable viscosity retention rate,Static adsorption viscosity retention rate). From dissolving formula, the adjustment of the polymerization and the process parameters of the drying process, grinding ratio of oil and dispersant, grinding screen division order such as the change of operation parameters for optimization. Improve the oil displacement with high molecular weight polyacrylamide product percent of pass of first class of the quality indicators. For oil field to provide more high quality surface active agent products,Ensure that 40 million tons of oil field goal,also to daqing refining companies to reduce product level brought about by the economic losses.Through a series of experiments, changing the dissolved liquid concentration, the amount of dissolved liquid pH, hydrolysis agent, REDOX system agent amount, initial temperature of polymerization, the dryer heat exchange way, dryer air temperature, wind pressure, grinding oil dispersants, etc. 8 trials. Produce molecular weight of polyacrylamide has reached the requirement of high molecular weight products, the quality of the products also received the larger ascension, achieved the result of this experiment is expected.
